and the kettle on the top stays hot all day
cheaper than putting the gas heating on

Example: Modern compact cameras which have no viewfinder but an LCD screen. Totally useless in bright sunlight.
More?

Some newer bulbs have mercury which makes disposal problematic - for those who bother to read the disposal instructions. These bulbs may present a skin cancer risk for susceptible people who get too close to them.
For many people the benefits and the energy reduction should be worthwhile, but it's not a completely no-brainer decision to switch to newer bulbs depending on the application and the eyesight of the intended users.

Originally posted by Dave2002 View PostThis is a mine field area. Some new bulbs don't last long, yet others are very good. Low energy ones are generally that - and there are benefits. However, the light levels are sometimes so low compared with supposedly comparable incandescent bulbs that users can't cope. This seems particularly to be the case with some older people who may find low light levels really problematic. Perhaps the spectrum of some newer bulbs is sufficiently different from older bulbs to cause some people great problems. The startup time and time to reach anything like full power can also be a problem. However I have bought very good LED bulbs - though at a vast expense. We also have first generation low energy bulbs which still work - and that must be after 20 years or more now surely. The big chunky ones!
